FABRICESCOURING ATTACHMENT FOR LOOlVIS.

SPECIFICATION forming part of Letters Patent No. 702,116, dated June 10, 1902. Application filed January 16,1902; Serial No. 89,957. (roman To all whom it mag concern.-

Be it known that I, PAUL SPINDLEB, a citizen of the German Empire, and a resident of I-Iilden, Rhineland, Germany, have invented certain new and useful Improvements in Fabric-Scourin g Attachments for Looms of which 7 the following'is a specification.

This invention relates to aloom attachment for scouring fabrics in which the securing blades are moved in a direction diagonal to the warp and weft, so that an effective scouring, without injury to the fabric, is effected.

In the accompanying drawings, Figure 1 is a sideelevation of my improved scouring attachment for looms; Fig. 2, a frontelevation. Figs. 3 and 4 are details of a modification of the cam and adjoining parts; and Fig. 5 an enlargedcross-section on line-A B, Fig. 4.

The letter Drepresents the frame of the loom, in which is hung an axially-reciprocating rock-shaft a, carrying the scouring-blades m. The drawings show a number of such blades arranged along the shaft; but in lieu thereof I may use a single blade of a length to extend over the entire width of the fabric g. The shape of the blades'and their arrangement may be modified at:pleasure, a spiral arrangement being, however, preferred.

The shaft or may be rocked and simultaneously reciprocated by suitable means. As illustrated, it carries a cam 25, having either a double spiral groove n, asin Fig. 2, or a single spiral groove n, as in Figs. 3 and 4.,

which is engaged by a fixed pin 6. The end of the shaft is provided with a collar a, between which and cam 25 it is grasped by-the forked end of a lever h, turning on fulcrum h.v The otherend of lever '77. is connected by rods d and 0 to a rock-shaftw. This shaft receives intermittent oscillating motion from power-pulley 8, having fixed or removable projections r and intervening cam-groove r.

The groove 1" is engaged by one end of a lever,

c, fast on shaft to. v

By means of the cam-groove r the lever o is vibrated in such a manner as to dwell be tween the vibrations and to impart through the parts a, w, o, d, and h a corresponding intermittent reciprocating motion ,to shaft a. As such shaft is thus reciprocated it is simultaneously rocked by the engagement of pin 6 with the groove of cam t.

What I claim is-- 1. A scouring attachment for looms consisting of a shaft carrying a scouring-blade,means for imparting a rocking movement to the shaft, and means for imparting an axiallyreciprocating movement to the shaft, substantially as specified.'

2 A scouring attachment for looms consisting of a shaft carrying a scouring-blade, a cam fitted upon the shaft, 2. pin engaging the cam, a power-pulley, and means for imparting an axiallyreciprocating movementfrom said pulley to the shaft, substantially as specified.

3. A scouring attachment for loomsconsisting of a shaft carrying a scouring-blade, a cam I fitted upon the shaft,'a.pi n engaging the cam,

a power-pulley having a cam-groove, a lever engaging the. same, a rock-shaft connected to the lever, and means foroperatively connecting the rock-shaft with the shaft, substantially as specified.
